This equipment is a relatively complicated apparatus.
During rigging, installation, operation, maintenance,
or service, individuals may be exposed to certain com-
ponents or conditions including, but not limited to:
heavy objects, refrigerants, materials under pressure,
rotating components, and both high and low voltage.
Each of these items has the potential, if misused or
handled improperly, to cause bodily injury or death. It
is the obligation and responsibility of rigging, instal-
lation, and operating/service personnel to identify and
recognize these inherent hazards, protect themselves,
and proceed safely in completing their tasks. Failure
to comply with any of these requirements could result
in serious damage to the equipment and the property in

GENERAL SAFETY GUIDELINES
which it is situated, as well as severe personal injury or
death to themselves and people at the site.
This document is intended for use by owner-authorized
rigging, installation, and operating/service personnel. It
is expected that these individuals possess independent
training that will enable them to perform their assigned
tasks properly and safely. It is essential that, prior to
performing any task on this equipment, this individual
shall have read and understood the on-product labels,
this document and any referenced materials. This in-
dividual shall also be familiar with and comply with
all applicable industry and governmental standards and
regulations pertaining to the task in question.
SAFETY SYMBOLS
The following symbols are used in this document to alert the reader to areas of potential hazard:
CAUTION identies a hazard which could
lead to damage to the machine, damage
to other equipment and/or environmental
pollution. Usually an instruction will be
given, together with a brief explanation.
NOTE is used to highlight additional
information which may be helpful to you.
DANGER indicates an imminently
hazardous situation which, if not avoided,
will result in death or serious injury.
WARNING indicates a potentially hazardous
situation which, if not avoided, could result
in death or serious injury.
External wiring, unless specied as an optional connection in the manufacturer’s product line, is
not to be connected inside the micro panel cabinet. Devices such as relays, switches, transducers
and controls may not be installed inside the panel. No external wiring is allowed to be run through
the micro panel. All wiring must be in accordance with YORK’s published specications and must
be performed only by qualied YORK personnel. YORK will not be responsible for damages/
problems resulting from improper connections to the controls or application of improper control
signals. Failure to follow this will void the manufacturer’s warranty and cause serious damage to
property or injury to persons.

The Control Cabinet contains lethal AC and DC voltages. Before performing service inside
the cabinet, remove the AC supply feeding the chiller.
The DC Voltage on the DC Bus will take 5 minutes to bleed o󰀨, after
AC power is removed. Always check the DC Bus Voltage with a
Voltmeter to assure the capacitor charge has bled o󰀨 before working
on the system.
NEVER short out the DC Bus to discharge the lter capacitors.
NEVER place loose tools, debris, or any objects inside the Control Panel Cabinet.
NEVER allow the Control Panel Cabinet doors to remain open if there is a potential for rain
to enter the panel. Keep doors closed and assure all latches are engaged on each door
unless the unit is being serviced.
WARNING!
CHANGEABILITY OF THIS DOCUMENT
In complying with Johnson Controls’ policy for con-
tinuous product improvement, the information con-
tained in this document is subject to change without
notice. Johnson Controls makes no commitment to

It is the responsibility of rigging, lifting, and operating/
service personnel to verify the applicability of these
documents to the equipment. If there is any question
regarding the applicability of these documents, rig-
ging, lifting, and operating/service personnel should
verify whether the equipment has been modified and
if current literature is available from the owner of the
equipment prior to performing any work on the chiller.
REVISION NOTES
Revisions made to this document are indicated in the following table. These revisions are to technical information,
and any other changes in spelling, grammar, or formatting are not included.
AFFECTED PAGES DESCRIPTION
3 Conditioned Based Maintenance program information added
CONDITIONED BASED MAINTENANCE
Traditional chiller maintenance is based upon assumed
and generalized conditions. In lieu of the traditional
maintenance program, a Johnson Controls YORK
Conditioned Based Maintenance (CBM) program can
be substituted. This CBM service plan is built around
the specific needs for the chiller, operating conditions,
and annualized impact realized by the chiller. Your lo-
cal Johnson Controls Branch can propose a customized
Planned Service Agreement that leverages real time
and historical data, delivering performance reporting,
corrective actions required and data enabled guidance
for optimal operation and lifecycle assurance. The pro-
gram will include fault detection diagnostics, operation
code statistics, performance based algorithms and ad-
vance rules based rationale delivered by the Johnson
Controls Connected Equipment Portal.
